ISOLATION AND DETECTION OF BORRELIA BURGDORFERI FROM HUMAN VAGINAL AND SEMINAL SECRETIONS
Middelveen MJ Bandoski C, Burke J, Sapi E, Mayne PJ, Stricker RB
Background: Previous epidemiological and immunological studies suggest
that infection with the Lyme disease spirochete Borrelia burgdorferi
could be transferred from person to person via intimate human contact
without a tick vector (Harvey and Salvato, Med Hypotheses 2003;60:742;
Stricker et al, J Investig Med 2004;52:S151).
Detecting viable spirochetes in vaginal and seminal secretions would
provide additional evidence to support this hypothesis.
Methods: Three North American patients with a history of Lyme disease,
one male and two female, were selected for the study after informed
consent was obtained.
Serological testing for B. burgdorferi was performed on all three
subjects. Blood and semen or vaginal secretions were used to inoculate
BSK-‐H medium for Borrelia culture. Motile spirochetes were detected in
cultures by light and/or darkfield microscopy, and cultured spirochete
concentrates were subjected to Dieterle silver staining, scanning
electron microscopy (SEM) and anti-‐B. burgdorferi immunohistochemical
staining for further characterization. Polymerase chain reaction (PCR)
testing was performed by two independent laboratories for specific
identification of the cultured isolates. Positive and negative controls
for immunohistochemical staining and PCR were performed in all experiments.
Results: Serum antibodies to B. burgdorferi were detected in all three
patients. Motile spirochetes were observed in culture fluid inoculated
with blood and genital secretions from the three subjects.
Morphological features of spirochetes were confirmed by Dieterle
staining, SEM and immunohistochemical staining of culture concentrates.
PCR testing confirmed that the spirochetes isolated from blood and
genital secretions were strains of B. burgdorferi, and PCR subtyping
indicated that the strains were B. burgdorferi sensu stricto.
Conclusions: The culture of viable B. burgdorferi in genital secretions
suggests that Lyme disease could be transmitted by intimate contact from
person to person.
